Descrição detalhada
Homonymous visual field loss is the loss of vision on the same side in both eyes. The most common types are hemianopia (the loss of one half of the field of vision) and quadrantanopia (the loss of one quarter of the field of vision). Hemianopia and quadrantanopia may cause difficulties in seeing objects on the side of the field loss. People with these types of field loss can compensate by scanning (looking) toward the side of the field loss. However, sometimes they might not scan sufficiently well resulting in delayed responses to hazards when driving. The purpose of this research study is to evaluate a new approach, "reminder-cue scanning training", to training people with homonymous visual field loss to scan when driving.
Participants will receive reminder-cue scanning training in the driving simulator.Typically there will be three training sessions within about a 2-week period. In addition, participants will complete an evaluation in the driving simulator before and after the training.

Number of Head Scans to the Side of the Field Loss
Prazo: Pre-training, Post-training (1 week)
|
Number of head scans per intersection to the side of the field loss. A validated algorithm was used to detect head scans, defined as lateral rotations of the head away from the straight ahead position toward either the left or the right, which exceeded a predefined threshold based on the participant's distance to the intersection: ≥ 4° (100 to 50 m to intersection), ≥ 6° (50 to 20m), ≥ 10° (20 to 0m).

Magnitude of Head Scans to the Side of the Field Loss
Prazo: Pre-training, Post-training (1 week)
|
Mean magnitude (in degrees) of head scans to the side of the field loss. A validated algorithm was used to detect head scans, defined as lateral rotations of the head away from the straight ahead position toward either the left or the right, which exceeded a predefined threshold based on the participant's distance to the intersection: ≥ 4° (100 to 50 m to intersection), ≥ 6° (50 to 20m), ≥ 10° (20 to 0m). The magnitude is the lateral angular extent of the scan measured from the straight-ahead position to the furthest lateral position to the left or right.
